The woman was brought out through the window of the property and taken, along with three other people, to the rest centre where she could be checked over by a GP.

A 92-year-old local man was rescued by British Red Cross volunteers earlier today after he became trapped in his house as flood waters rose in the city last night.

First aid is being provided for people affected by the cold and suffering from minor injuries and wheelchairs and other medical equipment is being transported from the Red Cross centre in Abergele.

Volunteers are also working with a local GP to arrange for replacement medication (such as insulin for people with diabetes) to be transported from Glan Clwyd Hospital, in Bodelwyddan, Denbighshire.

Elisa Gibson, 72, a great grandmother from Llys-Y-Felin, St Asaph, who is receiving support at the rest centre today said: "Everything here is perfect apart from there is no bath!"

Elisa, who was alerted at around 2am to the danger by a neighbour and later evacuated by the fire service, said: "One minute the water was just covering the floor and the next it was up to my knees.

"It was coming in through air vents and doors. I tried to brush it out but it was useless."

When Elisa was evacuated, her husband, Colin, stayed behind to save their two cats and eventually managed to carry them to safety through water that was up to his chin.

Elisa and her family will continue to be supported until they are able to find alternative accommodation.

Up to 100 people have turned up at a rest centre set up for flooding victims in St Asaph.

Denbighshire County Council set up the facility at St Asaph Leisure Centre after warnings to around 500 households in the city that there was a "high likelihood" the River Elwy would burst its banks and flood homes.

People started arriving at the centre at 7.45am, said a spokesman for Denbighshire County Council.

The river was to reach high tide at 10am.

"We’re waiting on the fall out (from high tide) if there’s going to be any.

"It’s a case of waiting and seeing what comes. We initially told people if they could stay with family and friends to do that and if that wasn’t an option to turn up at the rest centre."

The Elwy, which was still rising this afternoon, has reached a record high of 14ft 3in (4.35m) at St Asaph, making it more than 3ft (1m) deeper than its previous record of 11ft 4in (3.47m) in November 2009.

Typically, the river level at this spot varies between 3ft (0.90m) and 6ft 7in (2.02m).

The Environment Agency has issued two severe flood warnings in Wales – both for the River Elwy, one for St Asaph and one for the A55 to Rhuddlan – indicating a potential danger to life.

North Wales Fire Service say they have received over 130 calls since 6pm yesterday.

The Environment Agency currently has seven flood warnings and 23 flood alerts in place in Wales.

Areas affected by the flooding beyond St Asaph, include Abergele, Ruthin, in Denbighshire, and the Conwy villages of Llanfair Talhaiarn and Llansannan.

Police, fire and ambulance crews, the North and Mid Wales Trunk Road Agency and the Royal National Lifeboat Institution (RNLI) are all involved in rescue efforts.

Superintendent Peter Newton, of North Wales Police, who is leading the response, said: "We invoked an emergency response to the severe weather to ensure priority is given to any person at risk .

"Our priority is to protect and preserve life and we are working closely with our multi-agency partners to ensure the public are not at risk.

"North Wales Fire and Rescue Service is working to their full capacity. Since 6pm last night they have received over 130 calls and have appliances and rescue equipment out throughout the region responding to emergency calls.

"On their behalf, and in order they may prioritise calls I would ask the community to only call the Fire and Rescue Service if you believe lives are at risk and not just to properties being flooded when the householders are able to move upstairs or seek shelter with neighbours."

If your journey is essential then check first with Traffic Wales and plan your journey well in advance, take extra care and drive according to the conditions, the emergency services advise.

Also householders who need a sandbag are advised to contact their local authority as the fire service does not keep a supply.

RSPCA inspectors are also helping with the evacuation of residents in St Asaph.

The RSPCA has set up a holding centre for pets and teams in North Wales are also attending emergency calls in Bangor-on-Dee, in Wrexham, and Holywell, in Flintshire, where horses and other livestock are in difficulties.

Also volunteers from the British Red Cross in North Wales were deployed overnight.

On the request of Denbighshire County Council, Red Cross staff and volunteers helped to set up the rest centre in St Asaph’s leisure centre at midnight where they provided emotional support, as well as warm drinks, dry clothes and blankets.

David Hallows, Red Cross service manager for emergency response in North Wales, said: "Our volunteers have been responding to requests from both the local authority and the police to assist with ensuring the safety and well-being of members of the community.

"The rest centre in St Asaph is up and running and our volunteers have also been deployed in a Red Cross 4x4 Land Rover ambulance and another 4x4 vehicle to assist with the evacuation of sheltered accommodation for the elderly where we helped transport residents through flood water to safety."

Other volunteers from elsewhere in Wales along with additional 4x4 vehicles are en route to affected areas to help with the response efforts.

At 10.30am today Nigel Davies, senior services manager for emergency response, said: "It’s stopped raining but the river levels are still rising and it’s high tide at the moment. "We expect the rest centre to stay open until at least 6pm tonight.

"More volunteers from mid and north Wales are on their way to the scene at the moment to relieve those that have been there overnight and we also have volunteers on standby in Cheshire and Liverpool should we need them later this evening."

Insp Davies, of North Wales Police also said the regions roads were badly affected by the rising water.

The A55 is closed between St Asaph and Rhuddlan while the B5381 Lower Denbigh Road, St Asaph and the Craig Road, Denbigh and the B548 from Abergele to Llanrwst are also closed.Other road closures include the A4086 Pen-Y-Pass in both directions, the A5 near the A470 Waterloo Bridge, Betws y Coed, and in both directions between the B4401 (Corwen) and A494 (Druid).

Disruption has also been caused on the rail network. Buses have replaced trains between Llandudno Junction and Blaenau Ffestiniog until further notice.
